Pair light base colors with rich dark colors. Choose two colors, one dark color which will be the feature color, and another lighter color which will be the supporting color. If you have blue eyes, colors like black, grey, dark blue, purple or violet will do nicely as feature colors. If your eyes are green or hazel colored, you ought to use dark green, purple, deep khaki or brown colored eye shadows. Copper, grey, black or brown eye shadow also suit brown eyes.
